The work has been divided into two phases. In the first phase, pure diesel is tested in a CI engine and preparation of nanoparticles. Then in the second phase, performance characteristics are studied using the fuel added with nanoparticle in a four cylinder four stroke engine. The cerium oxide acts as an oxygen donating catalyst and provides oxygen for the oxidation of CO or absorbs oxygen for the reduction of NOx.

The paper had been explored and discussed for the effect of spacing between the heated vertical plates and heat input on the flow also the heat transfer characteristics inside the enclosure.
